The reduction gear with locking ring includes a motor 10, a reducer 20 connected to the motor 10, and a locking ring 30 provided in the reducer 20. It is conceivable that the reduction gear with locking ring also includes other functional structures, such as washers, set screws, etc., which are known to those skilled in the art and will not be described in detail herein.
Referring to fig. 1, the locking ring 30 is disposed on the speed reducer 20 and connected to the motor 10, and the motor 10 transmits torque to the speed reducer 20. The motor 10 is a common driving device in the market, and will not be described herein.
The decelerator 20 includes a main body 21, a mounting portion 22 provided at one end portion of the main body 21 in a length direction, an insertion hole 23 penetrating through the main body 21 and a central region of the mounting portion 22, and a clip tube 24 inserted into the insertion hole 23. The end surface of the main body 21 provided with the mounting portion 22 is provided with a counter bore 25. The counter bore 25 is used to cooperate with the motor 10 to assist in assembly.
The main body 21 is internally provided with a reduction gear and other components for reducing the rotation speed of the motor 10 transmitted to the main body 21 and improving the output torque, which is also the prior art in the market, and will not be described herein again.
The end surface of the mounting portion 22 facing away from the main body 21 is provided with a mounting hole 221, and the size of the mounting hole 221 is the same as the outer diameter of the locking ring 30, and is used for mounting the locking ring 30. An auxiliary through hole 222 is provided on the outer sidewall of the mounting portion 22. The auxiliary through hole 222 communicates with the mounting hole 221, and the auxiliary through hole 222 is used for a tool such as a screwdriver to pass through so as to adjust the locking ring 30. The auxiliary through hole 222 is used for matching the locking ring 30, and will be described below in connection with the locking ring 30.
The jack 23 and the clamp tube 24 are used for connecting with the output end of the motor 10. The clamping tube 24 is provided with a plurality of open slots 241 at intervals, which play a role in self-adaptive adjustment, and can be clamped on the output end of the motor 10 in use. The end of the clip tube 24 provided with the open groove 241 is disposed toward the direction of the motor 10 and extends into the mounting hole 221. The length of the clamping tube 24 is smaller than or equal to the length of the main body 21, so that the fit between the reducer 20 and the motor 10 is prevented from being affected.
The locking ring 30 includes a first locking portion 31, a second locking portion 32, a pin 33 connecting one end portions of the first locking portion 31 and the second locking portion 32, and a locking screw 34 connecting the other end portions of the first locking portion 31 and the second locking portion 32. The first locking portion 31 and the second locking portion 32 are assembled to form a circular ring.
